IBM Ledge

Update — Winter 2017: This building is on the same block as Trump Tower, and is blocked off for the next four — hopefully not eight — years.

High metal ledge on marble ground.

Bust — ♦♦♦♦♦: There are “No Skateboarding” signs posted. The building closes down after 10 P.M., but security may still come out and tell you to leave.

Location: 56th Street and Madison Avenue. Take the N, R or W to 59th Street-5th Avenue, and skate east for one block until you hit Madison. Make a right on Madison Avenue and skate south for three blocks. The spot is on the northwest corner.
